Fix [#32003] Triangulate fails for simple case.

Main problem was in poly_rotate_plane() (which rotates a ngon to make its normal aligned with Z axis), it did not handled the case where the normal was aligned but opposite to the Z axis (which had the consequence that, as with the T mesh of the given blend, all tested new edges inside face were detected as outside, and vice-versa...).

Additionnaly, I made a mistake in previous Triangulate commit (r48243) in bm_face_goodline, which could allow a few invalid triangles in some specific cases, fixed!

And done a bit of cleanup, as I was at it.
